Descrlption.--Leaves narrowly elliptical in outline, remarkably
uniform ill size and shape, 8. 5 cm. to 13 cm. in length and 3-5
cm. to 4.5 cm. in breadth. Apex usually bluntly rounded, sometimes
acute. Base matching the apex. Petiole medlumly stout,
3 cm. to 4 cm. in length. Midrib mediumly stout. Secondaries
slender, often obsolete, about I_ pairs, equidistant, parallel,
camptodrome, branching from the midrib at an angle of about
4o°. Wertiaries when seen transverse. Texture coriaceous.
This species was described originally from the Dakota Group
of Kansas. Professor Newberry described the Raritan remains,
which are abundant at the Woodbridge locality, as a new species,
and it has been kept distinct by Hollick, who recognized, however,
its practical identity with the Dakota Group plant.
There can be no question but that they belong to the same
species which is also recorded from Marthas Vineyard and Long
Island, and from the Woodbine formation of Texas and the
Tuscaloosa formation of Alabama.
Occurrence.--Woodbridge.
Collections.--N. Y. Botanical Garden.

This species was described by Professor Heer from the Atane
beds of western Greenland and compared with that author's
]lzlgnolia Capellinii, from which it differs in its thinner and more
numerous secondaries and its truncated base. It has also been
